Hi,
I have a XP pro. computer with NI VISA (and also Tek VISA).

When I click IO button in BenchVue, Keysight Connection Expert does not open but "NI Measurement & Automation Explorer" instead.

My 34401A is connected & visible in NI Explorer. But I cannot connect it to BenchVue.

Thanks for any clue.
Regards,
Michel.

You didn't specify which version of BenchVue you are using. If you are still on 1.1, it can't connect to Agilent Connection Expert because the our new name is Keysight. Please upgrade to the latest BenchVue (2.6) at www.keysight.com/find/benchvue. Let me know if the problem persists. If you are using 2.6, try running Connection Expert separately from BenchVue and use the "VISA 64 Conflict Manager" (in one of the drop-down menus) to make NI VISA primary. That may fix the problem with the instrument recognition. Please let me know how it goes.

  Hi Brian,
  
  I am running the last BenchVue (2.6).
  
  In fact I don't know how to launch Connection Expert separately. I haven't found this application anywhere after BenchVue installation !?
  
  Thanks,
  Michel.

    Oh, I see. Yes, if you already have another VISA library installed, the BenchVue installation does not also install Connection Expert. Thus, when you click the IO icon, it will launch NI MAX or Tek's equivalent. If you have multiple VISAs, BenchVue will show you a list of all of them when you click the IO icon and then you can choose which one to run. So, the connection problem appears to be in NI or Tek VISA. We have seen problems occur with multiple VISAs. You only need one, and if I had to pick one to remove, it would be Tek's. However, uninstalling Tek VISA also removes dll's that are needed by other VISAs. As painful as it may seem, remove Tek VISA, then use Control Panel to uninstall the IVI and VISA 64 Shared Components, then re-install NI VISA (repair should work, from Control Panel->Programs). If you want to use Connection Expert instead, which integrates nicely with BenchVue, then you can install it manually from the Keysight web site (ver. 17.1 is current).
    
    If you want to do any troubleshooting of your connection problem first, the best thing to do would be to use the VISA that you have installed (NI MAX) and try sending and reading commands to the instrument. You can send *IDN? to the instrument and it should respond with a model number.
    
    You might also want to get off of XP as soon as possible. BenchVue will be ending support for XP eventually, and Microsoft has ended support.

      Hi Brian,
      
      I have installed Keysight IO Libraries Suite v17.1 in addition to BenchVue.
      Now I can run Keysight Connection Expert and it has discovered my 34401A.
      Everything is now running OK.
      Thanks for your help !
      Regards,
      Michel.

        Glad to hear it Michel. Can you describe what steps you ended up taking? (Removing other VISAs, Shared Components, re-install, etc.)

        I have just installed Keysight IO Libraries Suite 17.1 (My NI & Tek VISA are still there, changed nothing).

        Thanks, good to know. CE probably installed itself as "secondary", although you might start it up and go look at which VISA is being used for which interface. You can do this in CE17.1 by selecting "Settings" and then "VISA Conflict Manager"
